Loose-LEAF BINDER.

Application led December 19, 1923. Serial No. 681.570.

T0 all whom t may concern:

Be it known that we, ARTHUR J. LLOYD and GEORGE A. OLsEN, citizens of the United States, residing at Chicago,`in the county of Cook and State of Illinois, have invented new and useful Improvements in Loose-Leaf Binders, of which the following is a speci'- cation. Y

This invention relates to loose-leaf binders and the like and is intended particu- -larly to be used to hold sheets for a visible record file. In this the sheets are placed one above the other, each sheet uncovering a portion of the bottom of the sheet below so as to permit identifying indicia such as the name of a firm or person to be placed thereon. By this arrangement, which in general is well known, all the bottoms are exposed and these are usually arranged in alphabetical order. l

When it becomes necessary to remove one of the record sheets from the center of a series, it is custoinary to lift the sheets above that one, remove it and replace the sheets above it, stepping them all down one space so as to keep the line of visible edges unbroken as before.

The primary object of this invention is to provide a means in the" file itself for accomplishing this rearrangement of sheets.

This and other objects as will later appear are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawings in which:

Figure 1 is a partial front inside elevation of the file open;

Figs. 2 and 3 respectively are sections on the lines 2 and 3 of Fig. 1;

Fig. 4 is a partial perspective of a back member removed;

Figs. 5 and 6 are similar views of a section of a channel member and of a bar;

Fig. 7 is a section on the line 7 of Fig. 3;

' Fig. 8 is a partial section on the line 8-8 of Fig. 7;

Fig. 9 is a section on the line 9 9 of Fig. 1, showing the prongs closed and locked; and

Fig. 10 is a similar view showing the prongs open.

over the sides of the openings 16 due to the action of the spring 17. The end 14a of the bar 14eXtends beyond the member 12 so that' the operator by pressing inwardly on the end 14a will cause the ears 15 to be moved to releasing position, when the members 11 and 12 can be swung about the hinge 13 to full open position as shown in Fig. 10.

A back member 18 having ends 19 is fitted about each of the members 11 and 12 as shown in Fig. 9, and is secured thereto in any suitable way as by means of tongues 20 which are adapted to be bent over and into the openings 21 in the members 11 and 12.4

Strips 22 are secured to the back members 18 in any suitable manner and to these is secured a flexible cover 23 of cloth, leather or the like and front and back leaves 24 and 25 are secured to said flexible cover.

The channel shaped member 11 has a. bar 26 slidably mounted in guides 27 within its outer flanges. A series of equally spaced prongs 28 is secured to the bar 26 and these project through openings 29 at the corners of the member 11. These slots or openings 29 are preferably of a length which will permit the entire series of prongs 28 to be moved up a distance equal to one-fourth the spacing between adjacent prongs on the same bar for a purpose which will be later explained.

A similar set of prongs 28a is'similarly mounted in the member 12 and these are likewise movable a distance one fourth the spacing between the prongs 28 and 28, or equal to one-half the spacing between adjacent prongs 28 and 28B.

With both the series of prongs draw down to the lower end of the slots 29 as shown in Fig. 1 the two 'series are interlocked with anequal spac-ing between adjacent prongs. These prongs are made arcuate as shown in Figs. 9 and 10, the arc of all being equal and being swung about the center of the hinge pin 13.

placed on the prongs one above the other so that a portion 30Et of each sheet is visible land upon which identifyin indicia such as the names of firms and in ividuals may be placed.

To remove one of these sheets the back is openedas shown in F ig. 10 and the desired sheet together with those that lie above it is then stripped off the prongs 28a'. To replace the sheets labove the one removed 'ft is necessary to move them all down a disl tan-e equalto the s acing of the openings 3l. This is accomp ished-by this device as follows. Having partially opened the binder, so that the prongs 28 are completely disengaged from the holes 31, the bar 26, is pushed up as far as the slots 29 will permit. The sheet to be removed and those lying above it are then removed over on the prongs 28 and the binder fully opened, thesel sheets meanwhile being carried upon the prongs 28.l The sheet to be removed is then taken ofi' the bottom, the prongs 28 drawn back to .their normal position as shown in Fig. '1 when the back is again brought to a closed position as shown in Fig. 9. The space created by the sheet which was removed will be'closed.

Tol insert a sheet the pile of sheets is first drawn to the left hand side, the prongs 28a withdrawn until they clear the pile of record sheets, when the prongs 28a can be slid up as far as'the openings 29 will permit.

The pile of record sheets is then opened at the desired point and moved over on the prongs 28, the binder then fully opened with 'these sheets still on the prongs 28a. The new sheet is then inserted on the prongs 28a .and the binder a ain closed with the new sheet inserted in t e proper place.

`For the purpose of moving the bar 264 a'lug 32 secured thereto extends through an opening 33 in the web of tlie channel meinber. By pressing on this the bar 26 may be moved up or down.

LA ledge 34 is provided in the members 11 and 12 adjacent the outer ends of the prongs 28 and 28 so as to prevent the record sheets working 'oli' the ends o f these prongs. v

It is to be understood, of course, that the record sheets shown constitute only one of several series of such sheets held by a single binder, each series being preferably separate from the next adjacent series by a larg-e spacer sheet which is substantially the size of the binder.

rhile we have shown and described certain embodiments of oui` invention, it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made without departing from the spirit and scope ofy the invention as disclosed in the appended claims, in which it isour intention to claim all novelty inherent in our invention as broadly as possible in view ofthe prior art.

We claim:

1. A loose-leaf binder comprising in combination, a pair of'4 channel shaped members having their flanges projecting rearwardly and with two of the flanges placed in contact with their tree edges hingedly connected, a bar slidably mounted upon each of the free flanges, prongs carried by each ',bar

projecting through slots in the web of the channel, said prongs curved concentrically tothe axis of said hinge, said bars adapted to slide with movement of its carried prongsl in said slots.' j

2. A loose-leaf binder comprising in combination, a pair of channel shaped members having `certain of their flanges in contact and with the rearward edge of said contacting flanges hingedly connected together, a bar slidably mounted upon each of the free flanges, prongs carried by each bar and curved concentrically to the axis of said hinge, -means to close the open side of said channels and means to limit the sliding movement of' said bar to a distance equal to one-fourth of the distance between adjacent prongs upon the same bar.

3. A loose-leaf binder comprising in cornbination, a pair of channel shaped bars having rearwardly projecting flanges with two of theflanges placed in Contact and their free edges hinged'ly connected, bars slidably mounted one upon each of the free flanges, prongs carried by each of said bars and projecting throughA slots in the adjacent web r of the channcl, said slots elongated sufiicie'ntlyto allow a movement of the bar of one-fourth the dist-ance between adjacent prongs upon the bar, means secured to each bar and projecting through the adjacent web whereby to cause movement of the bain ARTHUR J.
